WVR_GetAvailableFrameRates

WVR_EXPORT WVR_Result WVR_GetAvailableFrameRates(uint32_t frameRateCapacityInput, uint32_t * frameRateCountOutput, uint32_t * availableFrameRates)

Function to get available frame rates.

Use this function to get available frame rates for the HMD.

Version

API Level 12

Note

Supported since Runtime version 12 or higher.

Parameters

• frameRateCapacityInput: The capacity of the availableFrameRates array, or 0 to indicate a request to retrieve the required capacity.
• frameRateCountOutput: A pointer to the count of availableFrameRates written, or a pointer to the required capacity in the case that frameRateCapacityInput is insufficient.
• availableFrameRates: A pointer to an array of integer HMD available frame rates. It can be NULL if frameRateCapacityInput is 0.

Return Value

• WVR_SUCCESS: Get available frame rates successfully.
• WVR_Error_RuntimeVersionNotSupport: This feature is supported from Runtime version 12 or higher.
• WVR_Error_FeatureNotSupport: This feature is not supported on this device.
• WVR_Error_SystemInvalid: The runtime initialization was not finished.
• Others: Failed, please see WVR_Result for more information.

How to use

Here is an example for the function:

uint32_t frameRateCount = 0;
WVR_GetAvailableFrameRates(0, &frameRateCount, nullptr);
if (frameRateCount > 0) {
    LOGI("Get available framerate count: %d", frameRateCount);

    int availableFrameRates[frameRateCount];
    WVR_GetAvailableFrameRates(frameRateCount, &frameRateCount, availableFrameRates);
    for (int i=0; i < frameRateCount; i++) {
        LOGI("Available framerate: %d", availableFrameRates[i]);
    }
}
